2.25" ID Coil springs allow for spring rates greater than what is available in torsion bar sizes.

Progressive or Tender/Main spring combinations can be used resulting in a modern comfortable yet very
well handling ride.

Upper spring hat features our proprietary design sealed thrust bearing which proves to be the cleanest
solution in steering/spring rotation. Allows for maximum camber adjustments to be made.

Square threaded design is stronger and more resistant to dings, dirt, and binding associated with the
traditional Bilstein rsr struts. Square threads actually lock the spring perch in place under load, this is
backed up by a nylon tipped set screw for extra security.
